Going fast imp Feitoria Turtling is famous strat, and maybe you will not believe what i will say to you. Daut did this strat on Arabia vs MBL, he went for fast imp and spam Feitoria even that MBL was rushing him all the time, as coincidence i was spectating this game and i thougt MBL will win, but Daut had a great come back with his Feitorias and he won the game in the end. Next day T90 uploaded this game on youtube and it was completely sick game
I think it’s a question of how much of the time it will work. I’ve seen games a bit above 1100 where players just boomed and there were no early attacks, so I think you’d still win some of the time above 1100 with this strat. But at the same time, I’ve seen people below 1k who do a reasonable job of executing an earlier attack strat like Turks fast imp, which you’d lose to if both players reached imp at the same time and they attacked while you still had no army because you were busy making Feitoria instead.
